Getting Blank Page On Checkout after editing files with RTF editor

I upgraded and worked out a few things that needed changing to look like previous store.

I attempted to make a purchase to test the site.
I selected an item, clicked checkout, shipping options come up.
Left the default shipping selection as is and clicked on 'Continue Checkout' which should calculate taxes and such, but page comes up blank at this point.

Any ideas what I need to check out to get past this point?

If this help also,

This page is ok:
http://www.stuffupforgrab.com/store/index.php?main_page=checkout_shipping

This is the page that appears blank:
http://www.stuffupforgrab.com/store/index.php?main_page=checkout_payment

From reading other posts, I am not the only one with this problem.
I tried what others have suggested with no success.
This was an upgrade and I don't want to start all over with a new install.

I checked the payment_checkout file and the new and old are the same size.
That hasn't changed.

Usually a blank page is the result of a bad, missing or otherwise corrupt file ...

To help rule out the template, switch to the Classic Template ...

Other things could cause this, perhaps an URL to your site would help us see the problem ...

What version Zen Cart did you upgrade from?

I tried changing the templates and get the same blank page on both.

http://www.stuffupforgrab.com

Good to the shipping selection:
http://www.stuffupforgrab.com/store/index.php?main_page=checkout_shipping

Click on continue to goto page with taxes etc.,
At this point I get the blank page:
http://www.stuffupforgrab.com/store/index.php?main_page=checkout_payment

I upgraded from 1.3.7 to 1.3.8

I switched my site back to 1.3.8, so you can see for yourself.

Something else I noticed is that 1.3.7 and 1.3.8 give different quotes for shipping prices.

I am getting a lot of blank pages on your site ...

Are you calling images, banners, stats or something from other sites?

Sounds like you may have some bad files loaded throughout your site ...

A bad FTP of file(s) can cause these problems ...

I only get the one blank page. Everything else is ok here.
I don't access other sites other than the shipping modules Canadapost and Canpar.

Which payment modules do you have installed? Which ones are enabled?
What happens if you turn them all off and then try turning them on one-by-one and testing again (just refreshing the blank checkout_payment page)?

Might try similarly with tax rates.

Also, when you upgraded, did you use v1.3.8 or v1.3.8a? Be sure to use 1.3.8a when you do it again.

Furthermore, it is wise to always do your upgrades in a test area, not on your live site.

Using Paypal Express Checkout. I removed it and put COD.
Got the same blank page.

This is a copy of my 1.3.7 site (test site - upgraded to 1.3.8a)

I deleted all the tax setup and still blank page.

Okay.
What addons/contributions do you have installed on the site?
What exact steps did you follow to do your upgrade?

I used these instructions for upgrade:
http://www.zen-cart.com/wiki/index.php/Installation_-_Upgrade

The only thing I have added is the 'blue sky' template.
Maybe Canpar mod if it wasn't in original download.

I also removed the canpar and kept canadapost, still blank screen.

I will try uploading all the files again, but don't see the point since it was tried by others already with no success.

Your situation is apparently related to the checkout_payment page.

Most of the others I've seen are related to the checkout_process or checkout_success page ... and that's a result of an email problem, for which a fix has been published.

Since yours is failing on the payment screen, it's important to know which payment modules you have enabled. But, you keep talking about shipping modules instead ...

I already mentioned in a previous reply that I only use Paypal Express Checkout

Please upload a new file to your site, as follows:

name: /includes/local/configure.php (yes, create the "local" folder if needed)
contents:```

I tried the above and can't view any page of site.
Get the following instead:

Warning: Unexpected character in input: '' (ASCII=92) state=1 in /home4/stuffupf/public_html/store/includes/local/configure.php on line 2

Parse error: syntax error, unexpected T_STRING in /home4/stuffupf/public_html/store/includes/local/configure.php on line 2

It seems you've made a typo. There were no \ marks in the suggested code.
Please try it again.

Don't see how it's a typo. I copied and pasted what you put.

I tried 3 times with the same error.
On the fourth attempt, the error never came up.

On clicking on Continue Checkout, still get the blank page.

I opened the includes/local/config.php

And it contains the following now if it helps:

{\rtf1\ansi\ansicpg1252\deff0\deflang4105{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20 <?php\par if ($_GET['main_page'] == 'checkout_payment') define ('STRICT_ERROR_REPORTING', true);\par ?>\par
}

}

Where the heck is all that junk coming from? That's what I was referring to when I said "typo". You'll notice that what you quoted as being in the file is not what I had suggested you put in the file.

What software are you using to edit PHP files?
What software are you using for uploading and downloading files to/from your server?
If it's a microsoft product, dump it and use something reliable.

Perhaps you've got corrupted PHP files on your server as a result of using unreliable tools to do your file uploads ... hence the blank page during checkout.

I put exactly what you gave me and uploaded it with SmartFTP.

I give up. Going back to my 1.3.7.
Don't have the patience.
